How to read it
The Cross becomes the hand
The display is a celestial-pole view for the Southern Hemisphere. Crux rotates around the south celestial pole during the night, so the Cross can be read as a sky clock when the date, latitude and sidereal geometry are understood.
Position controls
Use time of day, day of year and year to explore daily rotation, seasonal drift and longer eclipse-cycle changes.
Preset moments
Solstice and equinox buttons give fast reference positions, while real-time mode turns the page into a live clock.
Learning boundary
This is an educational sky visualisation. Local horizon, weather, refraction and field navigation still need real observation checks.
